Thanks Raybo!
I got impatient and finally drilled a 1/8 in hole in the top of the handle and poured some of the well shaken Agrothrive out into a pint water bottle. Only a couple of drips and I can tape over the hole between uses for now. But I will e-mail Dragen to let him know what happened.
I just gave some of the mix (5 ml to 16 oz water) to several of my seedlings in cups. I'll report back if there are any exciting changes in the next few days/week.
